.i s claims. (01.251-23) This invention relates to valves, and particularly to an improved valve especially adaptedA for connecting an indicator or gage to the cylinder of an engine, pump, compressor or the like for ydetermining the pressure therein.

It is customary to connect a pressure indicator or other type of gage to the cylinder of an internal combustion cugina-such as diesels and the like, in order to determine the compression in the various cylinders so that the operating efliciency of the engine can be computed. It is preferable to connect the indicator or gage to the cylinder by means of a valve yso that the pressure of the gases issuing forth from the cylinder can be cut off after the pressure has been determined, and it is to a valve forsuchuse that the present invention primarily relates. While various valves for such a purpose have been heretofore suggested and'used, they were not as practical as they could be due primarily to their size and inconvenience in operation. In testing a cylinder, it is the usual procedure to connect first such avalve to the cylinder either permanently or temporarily. The valve is then opened to the atmosphere sol as to blow all dirt or accumulated carbon and tarl and other foreign matter out of the cylinder and uid passageways of the valve into the atmosphere before the indicator is attached in order to prevent fouling of the indicating instrument. The valve is then closed, the indicator attached to' the valve, and the valve again opened so that the gas pressure will pass through the valve to the indicator and be recorded thereon. It will be seen that such procedure is not only inconvenient and laborious, but requires a considerable amount of time to test a given `number of cylinders. f

According to the present invention, therev is provided a valve which is preferably attached to the cylinder permanently. It is relatively small and may be placed in such a location that would be prohibitive with the conventional type valve. The valve is so constructed and arranged that any foreign matter which may have accumulated in the valve passagewaysis blown therefrom into the atmosphere when the valve is partially open Without carrying such foreign matter into the indicator. When the vvalve has been fully opened, the valve passageways are closed to the atmosphere thereby permitting the vgases to pass through the valve to the indicator so as to indicate the correct pressure` Accordingly. lit is the general object Vof the i present Vinvention to provide `an;iinmyoved,valve forV connecting a pressure indicator to 'the cylinder of' an internal combustion engine or the like, having passageways which are open freely tothe atmosphere when the valve is in its closed or partially open position sov that the passageways are blown free of foreign matter by the gas pressure issuing forth from the cylinder and, at the same time, releasing the gases from the indicator,- and which are closed to the atmosphere when the valve is in its fully open position so asto permit the gases to pass through the passageways in the valve to the indicator to indicate the vcorrect pressure,

It is another object of the invention to provid an improved valve which is simple and compact in'its construction, and one which` consists of a minimum number of parts vwhich can beA easily and inexpensively machined and assembled.

Itis a further object of this invention to provide an improved valve which can be conveniently attached to and detached from the cylinder to be tested where space is limited and to which the indicator can be easily and quickly attached.

It is still another object of the present invention to provide an improved valve which will not stick or subject the parts of the valve to excessive strain due to relative contraction of the valve parts vcaused by the heat of the gases when the valve is in use thereby prolonging the life of the valve.

Various other objects and advantages of this invention will be more apparent in the course of the following specification and will be particularly pointed out'in the appended'claims'. i

In the accompanying drawings, there is shown for the purpose of illustration, one embodiment which my invention may assume in practice.VV

Referring more particularly to the drawings, the improved valve of my invention comprisesa body member 2Y having an opening '3, arranged axially thereof through which the fluid is adapted to pass. The inner reduced end portion 4 of the body member is cylindrical and is exteriorly threaded as at 5 forconnecting the valve to the cylinder or source of-iiuid supply;

This inner end portion has a diameter slightly smaller than that of the opening 3 so as to provide an annular passageway I therearound. On the inner end of the valve stem 6, there is arranged a valve head portion 8 having prefer- `ably ani annular; beveled or tapered; valve; portion 9 which. cooperates Vwith a corresponding'annul'ar Ibeveled or tapered seat-I arranged on the inner end of the body member 2 at the end of the open- .l

,The valve of my invention operates in the following manner. The valve is connected to the cylinder (not shown). to be. tested or the source of uid supply. by, means of the inner threaded portion. 5. The. indicator (not shown) is. then connected to the valveby screwing it. onto the outer threaded endportion 22 by means of the sleeve or coupling 23. Under normal operating conditions whenthe ,valve is closed, the indicator connection is rstseated as at 21. Continued turning of the indicator rotatesthe sleeve-like member I5., together with the Valve stem 6 at.- tachedthereto, and moves. the head away from its seat I@ to open thevalveto thecylinder due to, the action ofV the. threads I9, 20. When the valveT partially open itwill bev seenv that the gasesl pass from thecylinder into and through the annular passageway 'I and into the chamber 1a. Due to the fact that the. valveis only par.- tially open during the. initial turningperiod the gases will carry any foreign matter in thefc'ylinf der andv thepassageway tothe atmosphere out throughthe slots I8 in the side wall of the: body member 2 between the valve portion I6 and its back seat. I1. It is. the-purposeI of thev annular. shoulder. 2|l to, deflect the, gases into the. slots Ia and away from the. 4mirto I3.. Further turning of. the.- indicator and valve. stem seatsv thevalve portion I6 on itsback seat. I'I., as showninFig. 3., thereby 'closing Vthe chamber Ia .and annular pas.- sageway I to. theslots I8 and to the atmosphere* sothatthe gases are then `permitted to pass, from the: annular chamber. I into. and throughv thev ports I3. into 'the valyestempassageway. I2 and to the indicator thereby setting the. same in op-` eration.v

Y After; the pressure. has, been. recorded on the indicator, the. valve. is closed. by turning the n .v dicator and valve stem. 6 inthe opposite direc-- tion.. It will, beunderstoodthat the torque used in making, upf-the. indicatorconnection is; the` sameasthatused in freeing thread Zi-when open.. ingrthevalve,A and` making, the back seat at.I1.. It. isV well known. that vthe amount of torque required tofreea threadvaries directly asits pitch diamo eter and inversely as its pitch. Consequently when the.. valve stem; 6.i s, turned in thel opposite dir eotiom` lt will be -seen that. threads 25 having; alesse'r diameter and greater pitch than thread- 22 is, r therst to.. becf-reedl, and the valve,y portion Ibis, lifted from its:A baclgseat I1 and on continued turning the.V valveporton 9v is nally seated onitsseat.

As ay result ofV my invention, it will be seen that there is provided a new and novel valve which not only is simple and inexpensive in its construction, but one which is efficient and eiective in its use so as to reduce the time and effort materially for pressure testing 'any given number of cylinders or the like. It will be seen further that the use of my valve enables the operator to indicate a cylinder by attaching the indicator to the valve and opening the same in one turning operation and then closing the valve and removing the indicator by one turning operation in the reverse direction, thereby eliminating the step of blowing the valve free of dirt as a separate operation before the indicator is attached to the valve, which is a decided advantage.

While I have shown and described an embodiment which my invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised within the scope of my invention as defined in the appended claims.
